Setting of Relay Protection Setting for Distributed Photovoltaic Access Distribution Network Based on GSA Algorithm

The widespread integration of distributed photovoltaic power generation systems has transformed the distribution network from a traditional single power grid to a multi power grid, resulting in poor sensitivity effects. Therefore, this paper proposes a relay protection setting method for distributed photovoltaic access distribution networks based on the GSA algorithm. Design the specific solution process of GSA algorithm and extract real-time data of relay protection settings for distributed photovoltaic access distribution network; Determine the target value of real-time relay protection setting data from both current and voltage aspects, correspond to matching conditions, and obtain the setting result. The experimental results show that the tuning sensitivity of the proposed method is higher than 95%, and it has good tuning effect.
